Product functions and advantages
Source-load function One-key switching
The IT6000B series integrates two devices, a bidirectional DC power supply and a regenerative DC load. And the function keys are designed on the panel in a user-friendly way, so that users can easily use the IT6000B as a bidirectional programmable DC power supply or as an energy regenerative DC electronic load. It saves users the space occupied by the equipment, the cost, and the time spent on connecting the instrument to the object to be tested.

Bidirectional energy, seamless switching

The IT6000B series integrates the functional features of bidirectional power supply and regenerative load. Unlike traditional power supply and load, there will be short jumps and discontinuities in the middle when switching between positive and negative current. As a standard high-speed bidirectional power supply, the IT6000B series can achieve high-speed source and load current mode conversion, so as to perform fast and continuous seamless switching between output and absorption current, effectively avoiding voltage or current overshoot, and is widely used in energy storage equipment testing such as batteries, battery packaging and battery protection boards.

High energy recovery efficiency

The IT6000B series has an energy recovery function, which can recover electrical energy and then use it directly in the factory instead of consuming it in the form of heat energy. Its conversion efficiency can be close to 95%, which not only greatly reduces the user’s electricity cost, but also avoids the use of air conditioners or expensive refrigeration systems and reduces noise. Most ordinary electronic loads are energy-consuming loads. In addition to the high electricity cost, a large amount of greenhouse gases or harmful gases such as carbon dioxide, sulfur dioxide, and nitrogen oxides will be generated during the power generation process, which will harm the environment. Using the IT6000B series can reduce electricity consumption, not only saving money, but also reducing the emission of greenhouse gases and harmful gases.

Solar cell array simulation power application

The IT6000B series is equipped with SAS1000 solar cell matrix simulation software, which can simulate the I-V curve of the solar cell matrix. It has built-in SAS models of EN50530, Sandia, NB/T32004, CGC/GF004, and CGC/GF035. After the user simply sets the parameters, the I-V curve output can be simulated and a report can be generated to test the static and dynamic maximum power tracking performance of the photovoltaic inverter. The user can also edit any I-V curve with up to 4096 points of shielding to achieve dynamic cloud cover effect, or store 100 I-V curves under different light and temperature in memory, and set the execution time and execution order of each curve to test the long-term maximum power tracking performance of the photovoltaic inverter under different climate conditions.

Built-in multiple standard automotive test curves

Automotive electronic equipment may often encounter power transient interference during vehicle startup and operation. To ensure that the DUT can withstand these actual transients, users need to simulate the worst-case power transient conditions during the test. According to relevant industry standards, the IT6000B series has built-in LV123, LV148, DIN40839, ISO-16750-2, SAEJ1113-11, LV124 and ISO21848 standard automotive power network voltage curves. Users can directly call out the instantaneous voltage drop at vehicle startup and a variety of automotive electronic test pulse waveforms to perform performance tests on related automotive electronic products. 12V, 24V and 48V voltage levels are available.

CC&CV priority function

The IT6000B series continues the CC/CV priority concept proposed by ITECH, and continues to help users solve various stringent problems in long-term test applications, making applications that require high-speed power supply or no overshoot more flexible. Users can choose the response speed of the CC/CV loop and the loop working mode to determine whether the output is voltage high-speed mode or current no overshoot mode, which is suitable for testing of high-power integrated circuits, charge and discharge testing, and power transient simulation and characterization of automotive electronics.

Parallel technology

♦ The performance parameters after parallel operation are the same as those of a single machine

♦ The system does not need calibration after parallel operation

♦ The parallel operation adopts optical fiber transmission, which has strong anti-interference ability

♦ The digital parallel operation solution is adopted, and the optical fiber is fully isolated to effectively protect the equipment and the object to be tested
